Which was bigger in ancient Song Dynasty, Kaifeng Prefecture or Henan Prefecture?

There is no doubt that Kaifeng prefect is greater than Henan prefect, because Kaifeng is the capital of the Northern Song Dynasty.

In the Northern Song Dynasty, the state-county system was implemented in local division, and there were government, army and prison at the same level as the state, among which the government was generally located in more important and differentiated areas, such as Sijing. Or economically developed areas, such as Kaifeng in Tokyo (now Kaifeng in Henan), Xijing in Henan (now Luoyang in Henan), Yingtianfu in Nanjing (now Shangqiu in Henan) and Daming in Beijing (now Daming in Hebei).

The top government official is called "Yin" and the adjutant is called "Shao Yin", who also stayed in Beijing. When the prince (the emperor's brother or son) is the prefect, it is called Yin; When other officials served as the magistrate, they were referred to as "the magistrate" for short. For example, Bao Zheng, a famous upright official in the Northern Song Dynasty, served as a "prefect" rather than a "magistrate".

Kaifeng, the capital of the Northern Song Dynasty, is undoubtedly the highest, and the other three capitals are lower than Kaifeng, so Kaifeng is the highest among the major prefects. Especially in the early years of the Five Dynasties and the Northern Song Dynasty, Yin of Kaifeng Prefecture was concurrently held by the Prince, and was called the "Prince", which was equivalent to the candidate of the Crown Prince.

Zhu Youwen, the adopted son of Houliang, took Kaifeng Yin as the storage of Zhu Wen, the great ancestor of Houliang (not established, killed by his brother Zhu);

Li Congrong, the second son of the later Tang Dynasty, took and Henan Yin as the storage of Li Siyuan, the emperor of Tang Ming (killed during the rebellion);

Liu Chengxun, the eldest son of the later Han Dynasty, took Kaifeng Yin as the storage of Liu Zhiyuan, the great ancestor of the later Han Dynasty (not established, sealed after Wang Wei's death);

In the second week, adopted son Chai Rong took Kaifeng Yin as the storage place of Guo Wei, the great ancestor of the second week (established in Zhou Shizong).

These crown princes were established as the heirs to the throne of the silent prince. Those emperors who ascended the throne normally without the status of "silent prince", such as Li Conghou in the later Tang Dynasty, Liu Chengzuo in the later Han Dynasty and Chai Zongxun in the later Zhou Dynasty, did not have the status of crown prince before they ascended the throne.

What about the scene in the early Song Dynasty?

Before Song Taizu's death, Zhao Guangyi was the King of Jin and Kaifeng Yin, which was the title of Chai Rong before he acceded to the throne. Zhao is the younger brother of Hehe, and his work experience is the most representative. Successively Xingyuan magistrate, Jingzhao magistrate, Kaifeng magistrate. Kaifeng prefect is the highest-ranking prefect, and is vaguely the candidate for a new generation of crown prince.

At that time, he wanted to take Xiang Sanzi as the storage. After abolishing Zhao Kaifeng, he chose his son Kaifeng Yin, renamed Shouwang, and later named the Crown Prince.
